The Georgia Secretary of State is demanding answers from the Department of Homeland Security after an unsuccessful breach to the department’s firewall.

Secretary of State Brian Kemp talked exclusively with Channel 2 investigative reporter Aaron Diamant on Thursday, saying he was “mad as hell” after what he called a massive cyberattack on the agency’s network Nov. 15, traced back to a United States Department of Homeland Security IP address.

“It’s outrageous to think about our own federal government is doing this to us,” Kemp told Diamant.

Kemp told Diamant that the network’s firewall held up and there was no breech. But after the agency’s security vendor sounded the alarm, Kemp fired off a terse letter Thursday to DHS Secretary Jeh Johnson.

“We’re demanding answers to some of these questions, you know? Are they doing this to other states? Was it authorized or not? Who ordered this? Why is it being done and why weren’t we notified?” Kemp said.

Diamant used Skype to contact former FBI and Department of Defense cybersecurity analyst Willis McDonald on Thursday to get his take on the situation.
